contact list in skype for business

hi im trying to:

add a phone number as a contact in skype for business with a name

or add an email contact and associating it with a name so I can have a contact list, it seems possibly in Skype but not in Skype for Business, is this possibly in Skype for business, it worked in Lync before the upgrade a user claimed?

Is it also possibly to transfer contacts from an iphone to Skype for Business contacts?

best regards

Kjell
